3` y AUTOMOBILE RADIATOR.

Application` mea April 12, 1919. serial No; 289,540.

To all'wlwm it may 0011.061712(V f f Be it known that lLISAUL BERMAN", al citi- Zen of the United States, residing at New York city, inthe county and lState of New York, have linvented certain new'and useful Improvementsin lAutomobile Radiators, of

which the following'is'fal specification.

My invention relates to an improved automobile-radiatonand hasffor' its object to simplify the` construction o'f'su'ch devices, andto increase their efficiency.

The invention'. comprises a radiator structure including upper *and lower removable tanks in communication with the radiator tank, tubesconnecting theupper and lower tanks, fand grids for 'supporting the tubes and contributing tothecooli'ng action.

The invention is illustrated in the accompanying drawing, in which- Fig. 1 isa front 'elevational/view of an automobile radiator, certain of the grids and tubes being removed;

Fig. 2 is a perspective view ofA a number of tubes set in the lower'ftanks and a number of interposed grids;

Fig. 3 is a perspective view of one of the grids;

Fig. 4 is a vertical sectional view through the entire structure;

Fig. 5 is a perspective view of a grid with adjacent tubes and an upper tank thereon;

Fig. 6 is a perspective view of the lower tank;

Fig. 7 is a plan view of the blank from which the grid is formed; and

Fig. 8 is an elevational view of a reinforcing or strengthening comb for the grids.

Referring to the drawings, 10 denotes the permanent radiator tank having the inlet 11. The tank is provided with a pluralityT of outlets 12 only one of which is shown in the drawings formed in a vertical wallbelow the overhung portion 10a of the tank 10. Positioned beneath the tank 10 is a series of removable auxiliary upper tanks 13 each comprising a relatively deep box like portion 13:L and a rearwardly extending relatively shallow portion 13. The auxiliary tanks 13 are assembled in relation to the permanent tank 10 in the manner shown in Fig. el, the box 13a lying under the overhung part 10a of the tank 10 and the rela tively shallow rearwardly extending' part 131 of the auxiliary tank resting under the bottom rear wall 10b of the tank 10. Formed in the rear wall of the box 13a is an opening 13 which, when the device is assembled, will align with an outlet opening 12 in the permanent tank 10. The front wall of each auxiliary tank 13 is provided with lateral extensions 13d each having therein a hole 13 through which to pass rods 14 held by nuts 15 by means of which the auxiliary tanks are tightly secured in position. Interposed between the rear wall of the box like portion of the auxiliary tank and the lower front -wall of theA permanent tank is a gasket- 16 to'prevent leakage.

The lower auxiliary tanks are constructed precisely like the upper auxiliary tanks, one such lower tank being shown in Fig. 6, the lower tanks being reversed in position relatively to the upper tank when installed. The descriptiongiven above of the upper auxiliary tank will apply to the lower auxiliary tank and will not be4 repeated.

In Fig. 4,' the lower auxiliary tank is denoted generally by the character X and communicates with the lower permanent radiator tank 10X having the oulet 11.

*Interposed between the upper and lower auxiliary tanks and communicating with both thereof is a plurality of series of flat tubes 17. These tubes may be attached to both the upper and lower auxiliary tanks as by being soldered thereto, or in any other suitableV manner, and are additionally secured in position by means of the grids shown in perspective in Fig. 3. Each grid is preferably formed from a blank 18 (Fig. 7) said blank having transverse slots 19 in Vits body, spaced apart slots 2O at one longer edge thereof and slots 21 at its opposite longer edge. It will be noted that the slots 9.1 are formed in pairs, while the slots 20 are formed singly. The blank 18 is bent upon itself a number of times to form the grid of Fig. 3, so that the slots 19 are at the sides of the grid and the slots 20 and 21 are at opposite edges or ends of the grid. The comb 22 of Fig. 8 is employed by being inserted inthe aligned slots 2O and 21 and acts as a brace or strengthening member for each grid. The comb is soldered or otherwise secured in position and three combs are preferably used for each grid, as shown in Fig. 3. A grid 18 is interposed between each two series of adjacent tubes 17, the tubes having their forward edges flattened or bevelled as shown at 17a, and the grids having projecting ears or lugs 18a which overhang and engage the fiat edges 17a of the tubes Specification of Letters Patent` Patented Jan, 17, 1922, i

and act to prevent lshifting of the latter. The connection is somewhat like a mortise and tenon joint. One or more grids may be apportioned to each pair of upper and lower auxiliary tanks, and the tanks, the grid or grids and the tubes lying at opposite sides ot the grid may all be soldered together to form a removable unit as shown in Fig. 5, or the grids may be separately removable as shown in Fig. 2. I provide an additional fastening means for the grids and appurtenant parts in the formota moulding 23 which is preferably a rectangular Vframe the Vparts of which are joined atthe corners by pivots or pins 24. Such a unit may be removed fronr the radiatorstructure, incase of damage, by removing the frame 2,3 looseninglthe nuts and slipping the unit out over the bolts or rods 1 f .I i Y o j The water circulates through the device as ifollows:-vIt enters the permanent tank 1() through the inlet 11, then passes through the ports 12 and 13Cv into the -shallow portion l14h ofthe upper tank down through the radiator tubes'17, then through the ports 13e and 12 at the bottom into theA permanent lower tank 10X and through outlet 11x. The grids 18 present aflarge air coolersur- 'tace whicheontributes byicontact with the tubes to .cooling the waterv as itA .passes through the rtubes 17.

It will be noted thatl provide a compact structure divided into units each of which may be removed and replaced independently of all others. All the parts may be struck up by dies and may thus be readily standardized? vWhat I claim is 1. AnVA automobile radiator comprising radiator tubes having depressed seats at their forward edges, removable grids having the forward edges of said tubes, and a moulding consisting of pivotally interconnected sections engaging said ears to retain the structure in position.V v Y 2. In an Vautomobile radiator having a radiator core `consisting of a series of removable upper and Ylower auxiliary tanks having parallel .tubes `conneeting said tanks and removablel grids Ainterposed therebetween, the assembling of which'forms a removable .ears overhanging and engaging the seats at unit thereof, connecting means comprising SAULv BERMAN.
